Can anyone guide me to the warning message that comes when I run the SAP2000 model for Pushover analysis?
The Warning is"Analysis cannot find the solution at step no---for case:pushX
Subsequent result will not be available".
Dear friend,
For the pushover curve, it is required thar the structure be pushed to a predetermined dispacement/force capacity levels in increments (say 10increments).
The message is all because it is unable to sustain the load level assigned to the structue.So reduce the target load/displacement levels.and rerun.
Please also note that pushover bieng a nonlinear load case, inelasticity associated with members shall be properly modelled.
All the best and good luck....
Dear Jayarajan Puttatt ,
Thank you alots for your replying.... I tried to decrease and increase the null steps but then also I am facing this problem!!
Jayarajan Puttatt , Thank you for your advice, I found the solution for this warning. As you said the problem was in properly modelled for members... Thank you again..
Regards
@Hayder Aabbas , I am facing the same problem. Can you please provide details about how you solved your problem?
Jayarajan Puttatt, How can we do a force-controlled pushover analysis. Once I select the full load option in SAP2000 for force-controlled pushover analysis, I am not able to get the responses step by step. Even though I have given the option of multiple steps. Please help me out.
My structure is a aluminum frame with glass infill so the non-linearity is due to link elements and not hinges.
Regards
